Describe what a MIPmap is, how to create one, why one would want to use one, where one would be used and how one is used.
describe an algorithm which transforms a grayscale image into a black and white image by using half toning. Suppose that the black and white image has eight times the resolution of the grayscale image in each dimension.
Different types of visual artifact (‘aliasing’) take place if images are rendered by using only one sample per pixel.
a) describe at least three different artifacts which take place.
b) describe a straightforward technique to ameliorate these artifacts.
